Finally, when you find host 2, we need vdsm log from this host - the log
may help to understand why there was a bad checksum, and why the bad
checksum was not fixed when the next message was sent to the mailbox.

Or this less intrusive fix - restart vdsm on the host with host id 2.

To find the host with host id 2, look for this log on all hosts:

[vdsm.api] START connectStoragePool(..., hostID=2, ...

This will clear the mailbox with the bad checksum. Once cleared
the SPM will stop complaining about the bad checksum.

Are you sure this is the log line? the error from line 612 should  be:

mailbox %s checksum failed, not clearing mailbox, clearing new mail
(data=%r, checksum=%r, expected=%r)

Please open a bug and attach the interesting part of the log -  from
starting the SPM
until the first error was seen, and some errors after that.

It would be useful if you cam share the compressed log somehow.

We also need the contents of the inbox and outbox:

For iSCSI/FC domain, the logical volumes

/dev/domain-uuid/{inbox,outbox}

For NFS/Gluster, the files:

/rhev/data-center/mnt/server:_path/domain-uuid/dom_md/{inbox,outbox}

You can copy them with dd, compress, and attach to the bug.


> I just upgraded vdsm:
> $ rpm -qi vdsm
> Name: vdsm
> Version : 4.20.43

This started after the upgrade?

As first aid fix you can clear the inbox and outbox files like this:

1. Stop vdsm on the SPM host

systemctl stop vdsmd

2. Clear the mailboxes

For iSCSI/FC:

blkdiscard -z /dev/domain-uuid/{inbox,outbox}

For NFS/Gluster:

dd if=/dev/zero
of=/rhev/data-center/mnt/server:_path/domain-uuid/dom_md/inbox bs=1M
count=16 oflag=direct conv=fsync
dd if=/dev/zero
of=/rhev/data-center/mnt/server:_path/domain-uuid/dom_md/outbox bs=1M
count=16 oflag=direct conv=fsync

3. Start vdsm on the SPM host

systemctl start vdsmd

No. Qcow2 file is not actualy compressed, it includes compressed clusters.
This can be detected by looking at qcow2 metadata, but it is not exposed by
qemu-img.

Yes, this is engine bug so upgrading engine is enough.

[ovirt-users]Fwd: FOSDEM‘19 Virtualization & IaaS Devroom CfP

2018-11-22 Thread Piotr Kliczewski
A friendly reminder that Cfp is due by 1st of December.

Please submit your proposal using:

https://penta.fosdem.org/submission/FOSDEM19

-- Forwarded message -
From: Piotr Kliczewski 
Date: Tue, Oct 16, 2018 at 9:32 AM
Subject: [ovirt-users] FOSDEM‘19 Virtualization & IaaS Devroom CfP
To: users 
Cc: Doron Fediuck 


We are excited to announce that the

call for proposals is now open for the Virtualization & IaaS devroom at the

upcoming FOSDEM 2019, to be hosted on February 2nd 2019.

This year will mark FOSDEM’s 19th anniversary as one of the longest-running

free and open source software developer events, attracting thousands of

developers and users from all over the world. FOSDEM will be held once

again in Brussels, Belgium, on February 2nd & 3rd, 2019.

This devroom is a collaborative effort, and is organized by dedicated folks

from projects such as OpenStack, Xen Project, oVirt, QEMU, KVM, and

Foreman. We would like to invite all those who are involved in these fields

to submit your proposals by December 1st, 2018.

About the Devroom

The Virtualization & IaaS devroom will feature session topics such as open

source hypervisors and virtual machine managers such as Xen Project, KVM,

bhyve, and VirtualBox, and Infrastructure-as-a-Service projects such as
KubeVirt,

Apache CloudStack, OpenStack, oVirt, QEMU and OpenNebula.

This devroom will host presentations that focus on topics of shared

interest, such as KVM; libvirt; shared storage; virtualized networking;

cloud security; clustering and high availability; interfacing with multiple

hypervisors; hyperconverged deployments; and scaling across hundreds or

thousands of servers.

Presentations in this devroom will be aimed at developers working on these

platforms who are looking to collaborate and improve shared infrastructure

or solve common problems. We seek topics that encourage dialog between

projects and continued work post-FOSDEM.

Important Dates

Submission deadline: 1 December 2019

Acceptance notifications: 14 December 2019

Final schedule announcement: 21 December 2019

Devroom: 2nd February 2019

Submit Your Proposal

All submissions must be made via the Pentabarf event planning site[1]. If

you have not used Pentabarf before, you will need to create an account. If

you submitted proposals for FOSDEM in previous years, you can use your

existing account.

After creating the account, select Create Event to start the submission

process. Make sure to select Virtualization and IaaS devroom from the Track

list. Please fill out all the required fields, and provide a meaningful

abstract and description of your proposed session.

Submission Guidelines

We expect more proposals than we can possibly accept, so it is vitally

important that you submit your proposal on or before the deadline. Late

submissions are unlikely to be considered.

All presentation slots are 30 minutes, with 20 minutes planned for

presentations, and 10 minutes for Q

All presentations will be recorded and made available under Creative

Commons licenses. In the Submission notes field, please indicate that you

agree that your presentation will be licensed under the CC-By-SA-4.0 or

CC-By-4.0 license and that you agree to have your presentation recorded.

For example:

"If my presentation is accepted for FOSDEM, I hereby agree to license all

recordings, slides, and other associated materials under the Creative

Commons Attribution Share-Alike 4.0 International License. Sincerely,

."

In the Submission notes field, please also confirm that if your talk is

accepted, you will be able to attend FOSDEM and deliver your presentation.

We will not consider proposals from prospective speakers who are unsure

whether they will be able to secure funds for travel and lodging to attend

FOSDEM. (Sadly, we are not able to offer travel funding for prospective

speakers.)

Speaker Mentoring Program

As a part of the rising efforts to grow our communities and encourage a

diverse and inclusive conference ecosystem, we're happy to announce that

we'll be offering mentoring for new speakers. Our mentors can help you with

tasks such as reviewing your abstract, reviewing your presentation outline

or slides, or practicing your talk with you.

You may apply to the mentoring program as a newcomer speaker if you:

Never presented before or

Presented only lightning talks or

Presented full-length talks at small meetups (<50 ppl)

Submission Guidelines

Mentored presentations will have 25-minute slots, where 20 minutes will

include the presentation and 5 minutes will be reserved for questions.

The number of newcomer session slots is limited, so we will probably not be

able to accept all applications.

You must submit your talk and abstract to apply for the mentoring program,

our mentors are volunteering their time and will happily provide feedback

but won't write your presentation for you!

[ovirt-users] VMs paused - unknown storage error - Stale file handle - distribute 2 - replica 3 volume with sharding

2018-11-22 Thread Marco Lorenzo Crociani

Hi,
I opened a bug on gluster because I have reading errors on files on a 
gluster volume:

https://bugzilla.redhat.com/show_bug.cgi?id=1652548

The files are many of the VMs images of the oVirt DATA storage domain. 
oVirt pause the vms because unknown storage errors.
It's impossibile to copy/clone, manage some snapshots of these vms. The 
errors on the low level are "stale file handle".

Volume is distribute 2 replicate 3 with sharding.

Should I open a bug also on oVirt?

Gluster 3.12.15-1.el7
oVirt 4.2.6.4-1.el7

Regards,

[ovirt-users] How to change the master storage domain to another specific domain

2018-11-22 Thread Ladislav Humenik

Hello,

is there any plan to add the possibility (or working way) to change the 
storage master domain to a specific, let's say by admin chosen storage 
domain, without shutting down all guests and moving all other domains in 
to maintenance as described in this old solution: 
https://access.redhat.com/solutions/34923


Any API call or whatever will be welcome.

I confirm that using "-c" option the size of the converted image is the
same as the 0.10 version. Thanks.
I didn't find a way to verify in advance if an image is compressed or not..
is there?

I confirm that after updating the engine (not yet the hosts) from 4.2.6.4
to 4.2.7.5 fixes the problem, both for the displayed disk size inside the
gui bar during upload (1.5Gb and not 66Gb) and for the successful
completion.
